A partially methylated partially methylolated melamine composition comprising a fraction of highly polar monomers characterized by liquid chromatography elution ratios. The composition is useful as a crosslinking agent for coating resins and provides curable coating systems capable of fast cure response at relatively low curing temperatures.

Methylated methylolated melamine composition

Coating compositions comprising a partially methylated partially methylolated melamine and a polyfunctional compound containing on average at least two functional groups per molecule selected from the group consisting of carboxy, hydroxy, primary and secondary amide and urethane. The partially methylated partially methylolated melamine comprises a fraction of highly polar monomers characterized by liquid chromatography elution ratios. The coating compositions are stable at ambient temperature and capable of fast cure response at relatively low curing temperatures.

Coating compositions comprising a methylated methylolated melamine

A curable powder resin composition comprising an aminoplast and a polyester or polyacrylic resin. The aminoplast is a condensate of a methylolurea or methylolaminotriazine with an aliphatic alcohol and a reactive compound containing at least one reactive group selected from the group consisting of hydroxyl and amide.

Powder coating resin composition containing a dicarbonamide or

A process for preparing a free-flowing curable powder resin composition with a sintering temperature above 40.degree. C., comprising the steps of condensing a methylolurea or methylolaminotriazine with an aliphatic alcohol and a reactive compound containing hydroxyl or amide groups; blending the condensate with a polyester or polyacrylate; and grinding the blend to a powder of average particle size in the range of 20 to 150 microns.
